А онда ово што сад троше метан у колима, колико то помаже? Јер с једне стране смањује количину метана, а с друге стране убрзава хабање мотора пошто не раствара уље и горња карика се слабије подмазује. Сад колико које утиче, бемлига, ал можда неко зна.

UN Says Climate Genocide Is Coming. It’s Actually Worse Than That.
By David Wallace-Wells

...
As recently as a year ago, when I published a magazine cover story exploring worst-case scenarios for climate change, alarmism of this kind was considered anathema to many scientists, who believed that storytelling that focused on the scary possibilities was just as damaging to public engagement as denial.
...

Because the numbers are so small, we tend to trivialize the differences between one degree and two, two degrees and four. Human experience and memory offers no good analogy for how we should think about those thresholds, but with degrees of warming, as with world wars or recurrences of cancer, you don’t want to see even one.

At two degrees, the melting of ice sheets will pass a tipping point of collapse, flooding dozens of the world’s major cities this century. At that amount of warming, it is estimated, global GDP, per capita, will be cut by 13 percent. Four hundred million more people will suffer from water scarcity, and even in the northern latitudes heat waves will kill thousands each summer. It will be worse in the planet’s equatorial band. In India, where many cities now numbering in the many millions would become unliveably hot, there would be 32 times as many extreme heat waves, each lasting five times as long and exposing, in total, 93 times more people. This is two degrees — practically speaking, our absolute best-case climate scenario.

At three degrees, southern Europe will be in permanent drought. The average drought in Central America would last 19 months and in the Caribbean 21 months. In northern Africa, the figure is 60 months — five years. The areas burned each year by wildfires would double in the Mediterranean and sextuple in the United States. Beyond the sea-level rise, which will already be swallowing cities from Miami Beach to Jakarta, damages just from river flooding will grow 30-fold in Bangladesh, 20-fold in India, and as much as 60-fold in the U.K. This is three degrees — better than we’d do if all the nations of the world honored their Paris commitments, which none of them are. Practically speaking, barring those dramatic tech deus ex machinas, this seems to me about as positive a realistic outcome as it is rational to expect.

At four degrees, there would be eight million cases of dengue fever each year in Latin America alone. Global grain yields could fall by as much as 50 percent, producing annual or close-to-annual food crises. The global economy would be more than 30 percent smaller than it would be without climate change, and we would see at least half again as much conflict and warfare as we do today. Possibly more. Our current trajectory, remember, takes us higher still, and while there are many reasons to think we will bend that curve soon — the plummeting cost of renewable energy, the growing global consensus about phasing out coal — it is worth remembering that, whatever you may have heard about the green revolution and the price of solar, at present, global carbon emissions are still growing.
...

To avoid warming of the kind the IPCC now calls catastrophic requires a complete rebuilding of the entire energy infrastructure of the world, a thorough reworking of agricultural practices and diet to entirely eliminate carbon emissions from farming, and a battery of cultural changes to the way those of us in the wealthy West, at least, conduct our lives. And we need to do all of that in two, or possibly three, decades. As a comparison, simply the last phase of the recent three-stop extension of New York City’s Second Avenue subway line took 12 years. All told, from the first groundbreaking, the project took 45 years.

That is not to say it’s over or we’re doomed. Stalling warming below four degrees is better than surpassing it, keeping temperatures below three is better still, and the closer we get to two degrees the more miraculous. That is because climate change isn’t binary, and doesn’t just kick in, full force, at any particular temperature level; it’s a function that gets worse over time as long as we produce greenhouse gases. How long we continue to is, really, up to us, which is to say it will be determined in the province of politics, which is to say public panic like that produced by the IPCC report can be a very productive form of policy pressure.

Male HE u Turskoj. (African Journal of Agricultural Research Vol. 6(14), pp. 3284-3290, 18 July, 2011)

The principal negative environmental impacts of small hydropower plants in Turkey

3General Directorate of State Hydraulic Works, 24, Region Directory, Örnek District, 36100, Kars, Turkey.
Accepted 30 May, 2011
There has been a substantial increase in recent years in the number of small hydropower plants (SHP) as an alternative renewable energy source. SHPs are plants which have a capacity of 0.5 to 25 MW and are subject to the environmental impact assessment procedures different from those of other plants in Turkey. There are 903 small hydropower plants in the country including those with a license application under evaluation, those in the process of construction or production. The number of the plants is ever increasing with the newly developed projects. While offering ecological advantages from a global perspective, SHPs may cause some environmental impacts at the local and regional level. In the present study, 40 SHPs (4 in the process of production, 22 under construction, 14 with an application under evaluation) were investigated and evaluated on site and some recommendations made.

As Small Hydropower Expands, So Does Caution on Its Impacts
Small hydropower projects have the potential to bring electricity to millions of people now living off the grid. But experts warn that planners must carefully consider the cumulative effects of constructing too many small dams in a single watershed.

Btw, ako mislite da imamo problema sa malim HE u Srbiji, pogledajte ovo u Indiji:

But hydropower’s benefits have come at a cost. In June 2013, early and extraordinarily heavy monsoon rains fell for two days, streaming off Uttarakhand’s mountainsides, overflowing its rivers, and overwhelming scores of new dams. The flooding eventually killed almost 6,000 people, tore up 1,300 roads, took out nearly 150 bridges, and destroyed 25 small hydropower projects. The disaster seemed an act of God, but a government-commissioned said much of the blame lay elsewhere — on the new hydroelectric power infrastructure, which included nearly 100 dams, many of them smaller than 25 megawatts in capacity.

uh ala si ovo improvizovao...

u gradskom jezgru Istanbula  - naročito u kvartu Beyoglu -  oduvek je bilo veoma malo zelenih površina. ti referiraš na proteste zbog Gezi parka koji su u osnovi imali uspeha - eno Gezi parka živog i zdravog. nijedan veći zeleni prostor u Istanbulu nije diran, osim što je Erdogan na jednom brdu podigao sebi sultansku džamiju koja izaziva poprilično gađenje Istanbulaca. Turci jako vole da provode vreme u prirodi i da prave piknike i nikome ne pada na pamet da u to dira, a ta zemlja jednostavno nije tako skrojena da neko, kako kažeš, ukida prostore za okupljanja i socijalizaciju. nije to Singapur pa da možeš da mikromenadžuješ takve stvari, to je ogromna, vibrantna zemlja u kojoj se gro života odvija na ulici, uz čaj, ispred prodavnica, u parkovima, pored mostova, na obalama, na uličnim ćoškovima.

His black Porsche said “Gypsy” on it, and he wore a scarf around his head. He used to be a ballerina, and he was homosexual, and very hot for Iggy’s parts—body parts—and “yen” is a term that William Burroughs uses a lot describing the craving for heroin. So in “Lust for Life” there’s a line, “Here comes Johnny Yen again, with liquor and drugs and a sex machine,” and that’s Gypsy Johnny coming up to Wonderland Avenue with his scarves and his drugs and his motorized dildos and whatever else he had, his balloons full of Mexican heroin that was killing all of us.

Canada to boost nuclear power to help meet climate target (March 2018)

Canada, the second largest producer of uranium, will boost its reliance on nuclear energy to reduce its carbon footprint and will encourage other nations to do the same, public broadcaster CBC said Thursday.

The move would mark a change in the climate strategy Prime Minister Justin Trudeau's government unveiled just last December, which did not mention nuclear energy.

Ево још о крављем ригу/прдежу итд.

Instead of growing feed for livestock, the report says, cattle should be grazed on a rotational system that has the potential to make pastures both more productive and able to sequester carbon. Livestock should be fed “ecological leftovers,” or the scraps humans leave behind—food waste and crop stubble—instead of what has been specifically grown for them.

Наравно, то од Амера који се у јединице мере разумеју као Марица у криви курац

бламберг wrote:the Climate, Land, Ambition & Rights Alliance has presented its own self-described “radical” plan to keep global temperatures from rising more than 1.5 degrees Celsius (1.8 degrees Fahrenheit).

Не, идиоте, 1 целзијус је 1,8 фаренхајта, хтео си рећи 2,7. И како се "радикални" план разликује од радикалног?

Баш је чудо једно како у говору никад не користе "наводнике" (оно кад их цртају у вадуху кажипрстом и средњим прстом обе руке) у погрешном смислу, него само кад пишу.
